Description

An iron platform with self-cleaning function for high school students' experiments

technical field

The invention relates to the technical field of experimental devices for high school students, in particular to an iron stand with self-cleaning function for high school students' experiments.

Background technique

The iron stand is used to fix and support various instruments. The iron ring can be used instead of the funnel stand. It is generally used for experimental operations such as filtration, heating, and titration. It is one of the most widely used instruments in physical and chemical experiments. It is often used in conjunction with alcohol lamps. Use, the simple iron stand is widely used in teaching, through the teacher leading students to conduct simple physical and chemical experiments can promote the cultivation of students' divergent thinking. However, the existing iron platform for school experiments requires students to clean it consciously after the experiment. During the cleaning process, students sometimes accidentally come into contact with some corrosive chemical solvent residues or sharp debris, which is easy to cause harm to students. And it is inconvenient to clean it. During the experimental operation, the test tube needs to be placed in a separate test tube rack. For some schools with limited educational resources, sometimes the test tube rack is not enough, and it is very inconvenient for students to call reagents. For this reason, we propose An iron stand with built-in cleaning function and capable of storing multiple test tubes.
